In the U.S., advances in drilling technologies, such as horizontal drilling and hydraulic fracturing, have brought about a veritable energy renaissance.

Thanks to staggering production growth from shale oil plays previously thought inaccessible, U.S. oil output is the highest it’s been since at least 1998. Some experts are even suggesting that the shale revolution could help bring about energy independence as early as 2020.

But while the U.S. may have been a first-mover in applying advanced drilling technologies to shale fields, it’s not the only nation endowed with vast shale reserves. In fact, China may hold 1,275 trillion cubic feet of technically recoverable shale gas, according to data from the U.S. Energy Information Administration. If accurate, that’s nearly 50% more than America’s 862 trillion cubic of recoverable reserves.

Will China and other countries around the world see the same success with shale drilling that America has?

A global shale revolution?Probably not any time soon. According to Andrew Brown, head of international oil and gas production at Royal Dutch Shell plc (ADR) (NYSE:RDS.A), shale development in the rest of the world won’t proceed as quickly as it has in North America.

The lack of sophisticated equipment, highly skilled personnel, and the need for much more exploration would limit international growth in shale output, he said. Unlike in the U.S., where high initial levels of investment ensured that shale projects were brought online rapidly, projects in the rest of the world can be expected to take much longer.

Brown’s assessment is supported by Shell and other oil majors’ experiences with shale drilling outside of North America. For instance, Exxon Mobil Corporation (NYSE:XOM) retrenched from its operations in Poland last year after initial tests failed to produce commercial quantities of natural gas. Chevron Corporation (NYSE:CVX) echoed similar concerns, offering a bleak outlook for shale production potential in Europe.

Other barriers to shale development outside North America include legal hurdles, such as onerous regulations and political opposition to fracking in Europe, and resource limitations, such as shortages of water — a crucial input in the fracking process — in China.

China highlights challenges for global shale developmentIn fact, China’s situation is a great example of some of the major hurdles facing foreign shale development. Despite its vast potential reserves of shale gas, Chinese companies have virtually zero experience in shale drilling. As a recent auction highlighted, of the 16 firms that received rights to explore the country’s shale gas fields, not a single one had drilled a gas well before.

For instance, though oilfield services firms Schlumberger Limited. (NYSE:SLB) and Halliburton Company (NYSE:HAL) have shown a keen interest in developing China’s shale resources, the absence of clearly defined and enforceable patent and property protection laws has given them reason to pause.
